Have some LMT questions...

[captain harlock]

The 19 series are highend motors and I'm running my 1930/5 motor with 4s lipos with no problems at all( at such voltage you've exceeded the recommended rpm range by leaps and pounds). It's only warm or mid hot( you can hold it in your hand with no problems).
The only thing that is suffering of this crazy setup is the Mamba Max esc, but with a few tweaks here and there, you can make it happy.

Definitely I'm in love with the LMT, but I've no clue where to get them......hydro&marines do not charge credit cards, ductedfans.com is very lazy to help and FDM is no longer stocking them( just pictorially). Mike has already cut his relationship with them as far as I know( or is it the other way round?).

I want a 1940/5 for my MRX-4X conversion, the Neu is too big to fit in( I'll get a Neu for the MBX-5R, instead).

As far I know hydro&marine accepts Paypal

VWT4: how do you compare the performance of the Bigmaxx to the LMT 1950? Have you run either on 6s?

I run the BiGmaxximum in a 5kg Supermaxx and the Lehner 1950-7 in a 7kg LST2, so there are very diferent trucks..

Both with 5S lipos the SuperMaxx seems to be more powerfull but it's really 2kg lighter... The handling of the Pletty is smoother, maybe cause the 6 poles or the Schulze 18.149f controller, the motors stays always really cool.

I still have to test the BiGmaxx with the eagletree, but yesterday I got some info from the LST2: with 5S 20C lipos RPM were 36.000, 105A and 1600W, the motor ran pretty cool.


BTW Lehner recently opened an ebay shop: http://stores.ebay.de/LMTdirekt

i just put some figures in for a BM running 51/20, does anyone know what rpm ranges the Bigmaxximums can run at happily? (the estimated rpms are around 50,000) Here are the results:

Enter Front/Rear Differential Gear Ratio (?): UE 1/8 scale
Enter Transmission Gear Ratio: E-maxx 2nd gear
Enter Spur Gear tooth count (?): 51
Enter Pinion Gear tooth count: 20
Enter total battery voltage: 22.2v
Enter kv rating of brushless motor: 2300 kv
Enter tire diameter in inches: 5.8

Total Motor Speed (?):51060 RPM
Theoretical Vehicle Speed (?): 60.65 mph (97.43 km/h)
